ANSWER ASAP Study the photos you found in your “Mount St. Helens succession photos” search.

Scan the photograph you used here. Be sure to submit your photographs, too (i. e. scanned or digital images).

Questions
In one part of the activity, you looked at photographs and placed them in order. How did you determine the order that the photos should go in?

When looking at your pictures in order, describe the changes to the area. What changes happened first? Why do you think that is?

The gradual change in an ecosystem in response to environmental change is called succession. From what you have learned, how is Mount St. Helens an example of succession? Explain.

Look at time lapse photographs of the Scorch, standing dead forest from 4 and 7 years after the blast on the site http://www. mshslc. org/return-to-life/changing-landsca pe/. By what mechanism do you think these plants arrived in the new area? How did they benefit the ecosystem?

Colonizing plants help prepare the soil for the growth of other species of plants Look at time lapse photographs of the Scorch, standing dead forest from 17 and 30 years after the blast on the site http://www. mshslc. org/return-to-life/changing-landsca pe/. Are these different plants than you saw in the photographs from Question 2?

Comedians like to joke that the reason we havenâ€™t been visited by intelligent life from elsewhere in the universe is that aliens have been monitoring earthâ€™s broadcasts of intellectually embarrassing tv programs, like gilliganâ€™s island, fear factor, the jersey shore, and the jerry springer showand so consider us far too primitive to merit a visit. letâ€™s check the assertion that aliens could have been receiving them. tv programs are broadcast at a frequency of about 100mhz with about 100kw of total power in 30frames per second, which emanatesroughly uniformly in all directions. assume that interstellar space transmits these broadcasts without attenuation. no matter how smart they are, aliens would require at least one photon per frame to interpret our signals. findthe number of photons per unit time per unit area reaching a receiver on a possible planet in the nearest star system, which is about 4 light-years away (a light-year is the distance light travels in a year). if aliens aimed a receiver or detector directly at earth, how big (in diameter) would it have to be to receive a photon per frame
